Sample changer solutions
Radiometer Analytical, a Hach Company brand, has introduced its SAC850 and SAC950 Sample Changers capable of handling multiple combinations of titrations, direct pH, ion and conductivity measurements fast and efficiently. These changers can be connected to a TitraLab® titration workstation or a direct measurement meter with or without PC software for complete and effortless automation. The SAC850 and SAC950 are compatible with a selection of removable sample trays, and wireless RFID tags eliminate the need to program the sample changer each time a new type of sample tray is used. User-defined sample preparation sequences offer all the benefits of full automation

Curved bill check valve
The Curved Bill Tideflex® TF-1 Check Valve is designed to enhance sealing, especially in low-lying areas with little backpressure. The valve is constructed entirely of rubber, making it virtually immune to rust, corrosion and weathering. The curved bill of the TF-1 seals without backpressure, allowing for a tighter seal that eliminates gapping issues. The flexible bill also seals around entrapped debris. The headloss of the valve remains exceptionally low. The TF-1 also has a strong spring steel spine, enabling it to handle long-term water weight. The spine is at a greater vertical angle, making the TF-1 able to withstand the cantilever effect when water is flowing through the valve. Applications include highway runoff, flood control CSO/SSO systems, site drainage, stormwater discharge, sewer systems, coastal discharges, odor control or any application requiring backflow prevention.

Pre-cast concrete wet well
Romtec Utilities Inc. has introduced a 10-foot-diameter pre-cast concrete wet well, expanding the capacity of its complete lift station systems. The new 10-foot-diameter pre-cast concrete wet wells offer greater capacity for stormwater, wastewater and industrial applications. The new well size accommodates both duplex and triplex pump systems for maximum design flexibility. The larger well size and three-pump configuration offer wastewater and stormwater managers a cost-efficient way to handle their current needs, while planning for future events at the same time. The new size also makes it easier to locate a well in places where deep excavation is impractical, since it can offer the same capacity as a deeper 8-foot-diameter well, but in a shallower design

Rainwater harvesting carport
The Aguaport is a complete steel carport and rainwater harvesting system utilizing the vast area previously wasted on the lot. With a slight modification to a basic residential rain gutter, precious rainwater can be channeled to a cistern, barrel or underground tank

Energy dissipater
The Hydro Vortex Drop™ Shaft is a compact, single-shaft system used to dissipate the energy of falling water in order to protect infrastructure from noise, vibration and damage when conveying water to a deep tunnel or deep storage system. Major components of the system include an inlet structure, a vertical shaft, an energy dissipater and air separation chamber. The inlet structure provides a smooth transition from the inlet to the vertical shaft while the shaft transports the water to the lower elevation. The energy dissipater located at the base of the structure eliminates the energy inherent in the falling water as it removes entrained air, and conveys the water to the storage facility

Stormwater monitoring guidance
As part of an EPA grant, the Center for Watershed Protection and the University of Alabama have prepared six monitoring study designs, outlined in the project’s final manual, Monitoring to Demonstrate Environmental Results: Guidance to Develop Local Stormwater Monitoring Studies Using 6 Example Study Designs. This guidance is designed to navigate the stormwater manager through the complexities of implementing a monitoring program so they can be confident in their results and get the most out of their limited stormwater dollars. Each study design covers such essential elements as scoping, budgeting, and staffing needs as well as equipment and sampling requirements. This manual is available for free download at www.cwp.org

Membrane bioreactor
Bio-Microbics Inc. offers the BioBarrier® Membrane Bioreactor (MBR) to help meet the increasingly stringent needs of environmentally sensitive areas. The membranes and processes used in the BioBarrier® system act as an impenetrable physical barrier for nearly all common pollutants found in wastewater. Designed specifically for the unique needs of the onsite and decentralized wastewater industry, the system’s high-quality effluent can be discharged into most environments including surface irrigation and other re-use methods

Infiltration chamber
StormChamber is an open bottom, HDPE infiltration chamber which functions in both permeable and non-permeable soils for subsurface retention, detention, recharge and reuse of stormwater. It provides a higher level of nutrient and pollutant removal by taking advantage of the natural biological and physical properties of the soil. StormChamber systems mimic pre-development conditions by putting post-construction runoff back into the ground approximately where it used to go, maintaining base flow to streams, wetlands, lakes, ponds and countering salt-water intrusion in coastal areas. The SedimenTrap component of the StormChamber system eliminates the need for pre-treatment devices

Nutrient separating baffle box
Designed to treat the entire stormwater flow, the Nutrient Separating Baffle Box meets or exceeds NPDES requirements for capturing a wide variety of pollutants including TSS, sediment, debris, organic material, hydrocarbons, and trash. Because water flow is not ducted off-line for treatment, head loss is minimal and comparable to a large square catch basin. Existing watersheds can be easily retrofit with a Nutrient Separating Baffle Box without compromising the original design specifications of the current stormwater system

Chamber with internal manifold
CULTEC Inc. has added an internal manifold feature to the company’s Recharger 180 and 280 models. This feature introduces design flexibility to the stormwater management system and decreases the required installation footprint. Two side portals located on the chamber allow manifolding to take place at any point within the system, eliminating the need to build external manifolds, thereby condensing the system. High Volume Low Velocity (HVLV) FC-24 Feed Connectors, open on both endwalls, are inserted into the side portals to construct the manifold. The cross-feed capabilities enabled by the manifold’s side portals offer greater flow than that available with 18” diameter pipe
